Description

The High Energy cosmic Radiation detector (HERD) facility has been proposed to be installed onboard the future China’s Space Station (CSS).

HERD will address major problems in fundamental physics and astrophysics with the precise measurement of charged cosmic-rays and gamma-rays from few GeV to PeV energies by means of a large acceptance detector based on an innovative concept.

The detector consists of a very thick (3 lambda, 55 X0) calorimeter made of nearly 7500 LYSO crystals arranged into an octagonal prism, surrounded by a scintillating fiber tracker, a plastic scintillator detector and a silicon charge detector to precisely identify and measure high energy particles. Additionally, a transition radiation detector provides accurate energy calibration.

HERD is designed to accept incident particles from both its top and four lateral faces thus providing an effective geometrical factor one order of magnitude larger than that of current experiments.

The large geometrical acceptance of the system requires detailed studies to define an efficient trigger system, which is able to identify the event samples for science and calibration purposes and keep the trigger rate to the level required by the acquisition system.

We will present the studies performed with the use of up-to-date models based on the most recent data, detailed simulations of the detector response and a CSS model to define the HERD trigger strategy.
